Lake Mývatn is a veritable paradise for birdwatchers and there is a highly diverse birdlife to be found both on the waters of the lake itself and on its shores. Many waders and marsh dwellers make their home there, but Mývatn is probably best known for its unique duck species composition. During the summer months there are more species of duck gathered in and around its waters than anywhere else on the planet. Mývatn and its wetlands are protected as a nature reserve (The Mývatn-Laxá Nature Conservation Area). It is registered as one of the internationally important wetlands, along with the Laxá river which flows out of the lake.
